Title: Relay valve combined with a load-sensing proportion valve for a vehicle air brake system
IPC: B60T15/20
Filed: 1974-05-30
Abstract: 1469995 Vehicle air brake valves JIDOSHA KIKI CO Ltd 30 May 1974 [30 May 1973 (2)] 23988/74 Heading F2F A combined load-sensing proportion and relay valve for a vehicle air brake system has a first piston 5 responsive to a control pressure Pi which acts on the first piston directly and via a second piston 6 and spring 7, the movement of the second piston being limited by a stop 12 adjustable by a lever 15 in accordance with the load on the vehicle, the first piston co-operating with a closure member 1 to connect an outlet port 19 selectively to an inlet port 17 and to exhaust via the closure member and being responsive to the outlet pressure so that the latter is proportional to the control pressure, the constant of proportionality changing after the second piston engages the stop. In the embodiment of Fig. 4 (not shown), the stop is on a rod projecting axially through the first piston and the closure member, and in the embodiment of Fig. 5 (not shown) the stop is on the end of a lever projecting into the space between the pistons. In the Fig. 7 embodiment, the second piston 6 is on the opposite side of the closure member from the first piston and the spring 7 acts on the first piston via a pull rod 28, the stop 31 in this case co-operating with a cover 30 carried by the second piston. In Fig. 8 (not shown), the pistons are arranged similarly to Fig. 7 but are interconnected by a tension spring. In Fig. 9, the second piston 6 has a depending stem 38 with a stop 39 co-operable with a seat 30 for spring 7. In Fig. 10, an arrangement similar to Fig. 2 is provided except the position of the stop 117 is determined by a cam 112 carried by a lever 113 which at one end is coupled to the vehicle suspension via a rod 115 and which at the other end is connected by a pin 111 to a lever 110 pivoted to the valve housing. The cam has an active face 118 for adjusting the position of the stop in accordance with normal load variations and an idle face 119 which is centred on the axis of pin 111 and engages the follower 116 on the stop when a wheel of the vehicle drops into a depression. When the wheel hits a bump, the cam moves clear of the follower 116 and the stop moves to a position in which an abutment 127 thereon contacts the top of the valve housing. The position of pin 111 is adjusted using a screw 126 controlling the inclination of lever 110. Fig. 14 (not shown) corresponds to Fig. 10 except that follower 116  runs in a cam slot having an intermediate active section and two terminal idler sections. Fig. 15 (not shown) corresponds closely to Fig. 7 but the stop has a follower engageable with a cam having an intermediate active face and two terminal idler faces.

Filed: 1972-05-23
Abstract: 1373053 Classified stacking of differentlysized parts F MEYER & SCHWABEDISSEN 23 May 1972 [9 Sept 1971] 24075/72 Heading B8C An apparatus for the automatic classified stacking of a set of board, or sheet, portions which have already been cut, from a board, or sheet, into strips 7, 8, 9, at least some of which are of different widths, with the latter transversely divided so that the set comprises twelve portions A-L of different sizes, comprises a variable-cut saw unit 1, an extrusion device 2, a transverse displacement device 3, a lengthwise positioning device 4, and a lifting platform 5. In operating the apparatus the trailing edges of the board portions 6 emerging from the saw unit are engaged by a member 15 of the extraction device 2 which member 15 pushes the set along a table 12 and up against a straight-edge stop 16 in order to restore the portions A-L to the original shape of the board. A conveying member 17 of the transverse displacement device 3 then engages the rearward longitudinal side of the set A-L and pushes the set in a direction transverse to its length onto a table 19 and past an edge 20 at the top end of the stop 16 by an amount which corresponds to the width of the strip 7. The feed carriage 21 of the positioning device 4 then displaces the strip 7 with respect to the edge 20 and towards the table 23-of the lifting platform 5 by an amount which is sufficient to push the rear edge of the portion A into alignment with the front edge of the table 23. As long as the portions of board are identical they are successively pushed the same distance forward by the device 4 as the table is correspondingly lowered step-by-step by an amount equal to the thickness of a portion until a stack of the required height has been formed. The platform 5 is then raised to its uppermost position so that the next portion A, as it is fed forward, pushes the already-formed stack to the back of the table 23, as indicated in broken lines, to provide space for a fresh stack. If, on the other hand, the following board portion has a different size, the lifting platform 5 is displaced, transversely to the direction of movement of the device 4 by an amount equal to the width of the previously formed stack plus a separating space 23 so that a fresh stack is commenced. A turntable (26), Fig. 2, not shown, would alternatively be turned through a corresponding angle. Individual lifting devices may be provided on the platform 5 for each of the different sizes of board portions. Also, conveying elements may be provided on the platform 5.

Abstract: 678,542. Straightening. GLEASON WORKS. Oct. 5, 1950 [Oct. 22, 1949], No. 24387/50. Class 83 (iv). [Also in Group II] A method of heat treating and straightening an elongated, rotatable metal part comprises mounting the part, while hot, between centres and rotating it while exerting against it a pressure having a component perpendicular to the axis of rotation. As shown, applied to the hardening of a pinion, a heated pinion P is placed between centres 50, 60 by a loader 32 and rotated by rotation of the centre 60, the loader being first withdrawn. Pressure is applied at axially and angularly-spaced points by rollers 127, only one pair of which is shown, which may be moved into contact with the pinion by hydraulically-operated toggles, Fig. 5 (not shown). A door 115, operated by a lever, is then closed and quenching liquid admitted to harden the pinion which is kept rotating. When hardening is complete the liquid is drained from the chamber, the door 115 opened, rotation of the pinion stopped, and the loader operated to remove the pinion from the centres. The centre 60 is vertically adjustable to allow the pinion to be placed in position and also to allow pinions of different length to be handled, and both centres may be bored to allow a blast of air to impinge on the ends of the pinion to remove any dirt. The hydraulic, cam, and electric systems are also described, Figs. 15, 18, and 17, respectively (not shown).

Title: Improvements in or relating to calculating machines
IPC: G06F7/02
Filed: 1928-08-27
Abstract: 296,351. Jacob. M. Aug. 29, 1927, [Convention date]. Statistical machines.-In a record-card or strip machine for effecting calculations relating to interest, bank accounts, workmen's pay rolls, &c. the closing of electric circuits, by the passage of the perforated cards or strip beneath a series of multiple contacts, causes a number of relays to operate in accordance with the code of perforations the operated relays establishing the connection to the keyboard and control circuit of a multiple-bank calculating apparatus. The decoding is effected by translating devices which may be of the form described in Specification 262,794. The calculating machine is surmounted by a frame C, Figs. 1, 2, with as many spring- controlled rods t as there are keys T1. The rods t are adapted to be coupled to the frame C by means of pivoted rods with forked ends f and with the upper ends passing through a ring a formed on an extension of the armature A of a corresponding polarized electromagnet E. When the armature is released the fork engages the rod t and the lowering of the frame C by a cam Q1 on a motor shaft G effects the depression of the corresponding key. The shaft G carries several cams Q1 - - Q5 which can be coupled thereto by clutches operated at the desired time by solenoids. The cams are associated with rods B1 - - B5 for effecting depression of the frame C, the totals and sub-total keys, the motor release key, and the means for restoring the armatures of the electromagnets E. The electromagnets E are provided with four distinct windings in parallel with the four leads corresponding to the four code perforations and fourteen such electromagnets E1 - - E14, Fig. 3, are provided for the fourteen possible combinations of one, two, or three perforations, the shunt connections to one or more of the leads a - - d being arranged as shown to produce a de-magnetizing effect to cause release of the appropriate armature. In a modification, to eliminate errors due to misadjustment of the armature springs the shunts from the magnets E1 - - E14 are provided with circuit breakers to ensure the opening of circuits successively. An electromagnet with three separate windings is provided which is adapted to function when the digit in a column is zero so as to close the circuit of the electromagnet of the clutch for lowering the frame C. The windings of this magnet receive current from a constant source, from a source through contacts on the armatures of the electromagnets E, and from that traversing the magnets E, the latter being in the opposing direction to that of the other two. Circuit arrangements are described for effecting a control of the calculating machine when performing calculations according to any one of the four rules, for registering results obtained from perforated calculating tables, for verifying two numbers and comparing the relative values of the same, and for automatically taking totals and sub-totals of groups of cards.
